Different Types of Mould
Understanding the different classifications of mould can help you to determine whether or not a professional eye is needed. Mould is organized into three different groups that are categorized by the effect they have on humans. Though some mould may be more severe than others, it does not discount the severity of mould as a whole, and what it can do to your health if not controlled.
Allergenic mould aggravates allergies and usually do not cause any serious health effects other than discomfort. Most people who are encounter this kind of mould, are already prone to allergies and/or have asthma. Symptoms can consist of itchy eyes and throat, and maybe a slight rash. When the seasons change, mould grows on vegetation outside that is decomposing from the winter, and mould spores can enter the lungs causing a reaction.
Pathogenic mold is when a reaction to mould turns into an infection. Normally a person with capable health can naturally fight off these infections, but people with immune system problems, young children, and infants can become sick easily. These kinds of mould can cause pneumonitis, which is inflammation of the lungs. Bipolaris, a kind of Pathogenic mould, usually can be found outside on plants and in the soil. It has brownish black consistency that sometimes can be difficult to spot, given its location.
The last kind of mold, toxic mold, can be tricky to categorize. Most people associate black mould with being toxic, and although this is true in many cases, not all toxic mould is black and not all black mold is toxic. Toxic mold produces what is known as Mycotoxins, and is poisonous to humans and animals. Though usually there is some kind of mould in most homes, it does not mean it is toxic mould. Many times, the only way to be absolutely sure is to send a sample to the lab using a trained specialist. However, just because mould is not toxic, it does not mean that your home is safe. Penicillium is an example of a toxic mold and its spores contain the highest concentration of mycotoxins. Aspergillus is another type of toxic mould that with overexposure can cause damage to the brain, heart, kidneys, and be especially detrimental to the liver. Stachybotrys is a slimy mold that does not transfer its spores through the air as effectively as other molds. Because of this, and its inability to compete with other bacteria, it is difficult to obtain a sample. It tends to be the most frequent of toxic moulds because it grows quickly, and it can thrive on a small amount of moisture.
